Verolme, E.K. (author), van der Voort, M.M. (author), Smits, R. (author), Weerheijm, J. (author), Koh, Y.H. (author), Kang, K.W. (author)There is limited knowledge on deriving the strength of an explosion based on the observed explosion effects. Existing methods are based primarily on the effects of blast overpressure on surrounding structures. Window breakage and structural damage are well studied and are widely used to derive most probable explosion strengths. Other explosive...article 2018

(author)An important blast injury mechanism is the rupture of the lungs and the gastrointestinal tract. In explosives safety studies and threat analysis the empirical model of Bowen is often used to quantify this mechanism. The original model predicts the lethality for a person in front of a reflecting surface caused by simple Friedlander blast waves....article 2016

Verreault, J. (author), van der Voort, M.M. (author)Multi-layered materials with alternating impedances as a mean to mitigate sympathetic detonation is considered in this investigation by studying the wave scattering and energy absorption phenomena. This is achieved using an analytical wave-tracking model that accounts for the different wave interactions within and at the interface of each layer....conference paper 2015

van der Voort, M.M. (author), Conway, R. (author), Kummer, P.O. (author), Rakvåg, K. (author), Weerheijm, J. (author)An accidental explosion in an ammunition magazine may break-up the structure and cause a significant debris hazard. Experimental and theoretical research mainly focusses on the break-up of the reinforced concrete or brick magazine walls. The behaviour of the door has usually been ignored in the derivation of Quantity Distances (QDs) and risk...conference paper 2015

Weerheijm, J. (author), van der Voort, M.M. (author), Verreault, J. (author), van den Berg, A.C. (author)Tunnel accidents with transports of combustible liquefied gases may lead to explosions. Depending on the substance involved this can be a Boiling Liquid Expanding Vapour Explosion (BLEVE), a Gas Expansion Explosion (GEE) or a gas explosion. Quantification of the risk of these scenarios is important to take informed decisions on tunnel design and...conference paper 2015

(author)A mass detonation of stored ammunition may lead to devastating injury, material damage, and asset loss. Such a scenario can be initiated by an external (fragment or bullet) impact, or the detonation of nearby ammunition articles, leading to sympathetic reaction/detonation. At a military base, sympathetic reactions between storage modules are...public lecture 2013

Boot, H. (author), van der Voort, M.M. (author)Predicting potential consequences of Vapor Cloud Explosions (VCEs) has always been an important issue in safety assessments, because of the devastating damage that this phenomenon can create on (petro chemical) production sites. Although the TNO Multi-Energy method has been recognized as one of the best methods to predict blast overpressures of...conference paper 2013

(author)The need for transportation and storage of CO2 in bulk quantities is likely to increase in the near future. The handling of CO2 on such scale gives rise to a number of technological challenges and safety aspects. The accidental rupture of a vessel containing liquefied CO2 may lead to a Boiling Liquid Expanding Vapour Explosion (BLEVE). Whether...article 2013

van Doormaal, J.C.A.M. (author), van der Voort, M.M. (author), Weerheijm, J. (author), TNO Defensie en Veiligheid (author)Risk analysis tools use probit functions to quantify the risk of lethality due to glass breakage. These probit functions are often based on data for an average sized or standard sized window. In reality however, there will be a range of window sizes and thicknesses. As a result, the current probits have the following shortcomings: - The...conference paper 2010

(author)Explosive loading of a reinforced concrete ammunition magazine may result in break-up and launch of debris. Since debris throw is one of the major hazards in case of an accidental explosion, it is of high importance within risk assessment tools.
